Description

Technical Field

[0001] The present invention relates to the technical field of dust reduction, and in particular to a construction dust reduction device and a use method thereof. Background Art

[0002] Construction can effectively reduce dust through a variety of means, thereby improving the construction site environment, protecting the health of workers and reducing the impact on the surrounding environment, mainly including wet dust reduction, covering materials, installing retaining walls, closing the work area, using vacuum equipment, etc.

[0003] Among them, special dust collection devices are used for construction machinery, tools and equipment to clean the dust on the ground and equipment in time to avoid dust generation. The filter components on the inner wall of the dust collection equipment need to be cleaned or replaced after long-term use. If the filter components are not cleaned, the dust adhering to them will block the air intake flow, reduce the dust removal effect, and increase additional cleaning work. Therefore, those skilled in the art provide a construction dust reduction device and a method of using the same to solve the problems raised in the above background technology. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the background technology and to provide a dust reduction device for construction and a method of using the same.

[0006] Preferably, a dust collecting box is connected to one side of the lower end of the installation box, a discharge pipe controlled by a valve is provided at the lower end of the dust collecting box, and a guide plate corresponding to the dust collecting box is provided on the inner wall of the lower end of the installation box. The dust collecting box collects the dust sucked into the interior of the installation box and discharges it for cleaning through the discharge pipe, and the opening and closing of the discharge pipe is controlled by a valve.

[0007] Preferably, a rotating shaft 1 is rotatably installed inside the installation box, a driven wheel 1 having a radius larger than that of the driving wheel 1 is sleeved on the outer wall of the lower end of the rotating shaft, and a belt 1 is rotatably installed inside the driving wheel 1 and the driven wheel 1. The belt 1 links the driving wheel 1 and the driven wheel 1, and because the radius of the driving wheel 1 is larger than that of the driven wheel 1, when the driving wheel 1 rotates, the driving wheel accelerates the driven wheel.

[0008] Preferably, a rotating shaft 3 is provided at one end of the cam disc, a bevel gear 2 is sleeved on the outer wall of the rotating shaft 3, a bevel gear 1 meshing with the bevel gear 2 is sleeved on the outer wall of the upper end of the rotating shaft 2, and a protective box is sleeved on the outer sides of the bevel gear 1 and the bevel gear 2, which is rotatably mounted with the rotating shaft 2 and the rotating shaft 3 and fixedly connected with the inner wall of one side of the installation box. The bevel gear 1 and the bevel gear 2 are linked to the rotating shaft 2 and the rotating shaft 3, and the rotating shaft 2 and the rotating shaft 3 are shielded because they are rotatably mounted with the protective box, so as to prevent the dust entering the interior of the installation box from causing wear on the tooth grooves of the bevel gear 1 and the bevel gear 2.

[0009] Preferably, the installation box is provided with symmetrically distributed guide rails, and both ends of the guide frame are provided with sliders slidably mounted on the outer wall of the guide rails. The guide frame slides on the outer wall of the guide rails through the sliders, and the guide frame is longitudinally guided.

[0010] Preferably, a cam block is provided at one end of the cam disc and is slidably mounted inside the guide frame. A mounting plate is provided at one end of the guide frame. Springs are arranged between the mounting plate and the travel plate and are equidistantly distributed. The cam block rotates at one end of the cam disc and presses the guide frame with the cam disc as the axis during rotation. The movement of the guide frame in one cycle is located at twice the distance from the cam block to the cam disc.

[0011] Preferably, the mounting plate is embedded with equally spaced sleeves, and the travel plate is provided with a guide rod which is slidably inserted in the sleeve and located inside the spring. The guide tube slides inside the sleeve to guide the travel plate laterally and limit the spring during the extension and retraction process.

[0012] Preferably, pulleys are arranged at the four corners of the lower end of the base. The base is supported by the pulleys for sliding at the four corners of the bottom, so that the base can slide on the ground.

[0013] Preferably, a universal tube is provided at one end of the suction hood. The universal tube can be completely bent and shaped through the internal structure, and the opening direction of the universal tube can be adjusted.

[0014] A method for using a construction dust suppression device, the steps of using the dust suppression device are as follows:

[0015] S1: When the suction dust removal equipment is used for dust reduction treatment, because the radius of the driving wheel 2 is larger than that of the driven wheel 2, the rotational force output by the motor at the output end passes through the driving wheel 2, and under the linkage of the belt 2, it accelerates the transmission wheel 2, thereby driving the impeller to rotate at high speed, generating a strong suction force, which acts on the dust generation place through the suction pipe, the connecting tube and the suction hood, and sucks and collects the dust;

[0016] S2: During the dust removal process, the base of the dust removal equipment slides on the ground through a pulley, which is convenient for moving to a designated position, providing convenient movement conditions for the dust removal equipment. The suction hood can adjust the suction angle through a universal tube to deal with dust generated in the high or low space of the dust removal equipment;

[0017] S3: When the filter intercepts the dust, the driving wheel 1, the driven wheel 1 and the belt 1 are linked to drive the rotating shaft 1 to rotate, and the bevel gear 1 and the bevel gear 2 are linked to drive the cam plate to rotate. The cam plate is guided by the soil blocks on the side to squeeze the guide frame installed to move back and forth longitudinally, thereby driving the brush to scrape the filter to remove dust. The filter component is automatically cleaned when the dust removal equipment is in use.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] When the impeller inside the pump casing of the present invention rotates at high speed, the suction force generated enters the connecting cylinder through the suction pipe, and then acts on the outside through the suction hood, corresponding to the place where dust is generated by equipment during construction, and then the dust is sucked and dust reduced. While the filter intercepts the sucked dust on one side of the installation box, the stroke plate continues to move back and forth longitudinally, driving the brush to scrape the outer wall of the filter to make the adhered dust fall off. The filter component is continuously cleaned during use, avoiding manual cleaning. At the same time, the self-cleaning structure and the negative pressure suction structure are driven by the same power source motor, which reduces energy consumption during use.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figures 1 to 8 , the present invention provides three embodiments:

[0031] Embodiment 1:

[0032] A construction dust suppression device comprises a base 1, an installation box 6, a pump housing 18, a motor 19, a rotating shaft 1 23, a guide frame 31 and a cam plate 35. The motor 19 is arranged at the lower end of the installation box 6, and the output end of the motor 19 is arranged with a driving wheel 1 20 and a driving wheel 2 24. A rotating shaft 27 is rotatably installed inside the pump housing 18, and an impeller 28 rotatably installed on the inner wall of the pump housing 18 is sleeved on the outer wall of the rotating shaft 27. A suction pipe 4 is arranged at the suction end of the pump housing 18, and a connecting tube 5 connected to the installation box 6 is arranged at one end of the suction pipe 4. A filter screen 11 is arranged inside the installation box 6, and one end of the installation box 6 is connected to a suction hood 7 installed with a corresponding connecting tube 5. A driven wheel 25 with a radius smaller than that of the driving wheel 24 is sleeved on the outer wall of the rotating shaft 27, and a belt 26 is rotatably sleeved inside the driving wheel 24 and the driven wheel 25.

[0033] A dust collecting box 2 is connected to one side of the lower end of the installation box 6, a discharge pipe controlled by a valve is provided at the lower end of the dust collecting box 2, and a guide plate 9 corresponding to the dust collecting box 2 is provided on the inner wall of the lower end of the installation box 6;

[0034] Pulleys 3 are provided at the four corners of the lower end of the base 1;

[0035] A universal tube 8 is provided at one end of the suction hood 7;

[0036] In this embodiment, the base 1 slides on the ground through the pulley 3 at the bottom, and after moving to the designated position, the suction hood 7 is adjusted to correspond to the dust generation location. The universal tube 8 is usually made of highly elastic materials, such as rubber, plastic or metal hose, etc. These materials have good flexibility and ductility, so that they can bend without breaking when external force is applied. Multi-layer spiral coils or bending structures are usually used. This design enables the pipeline to have better bending performance and adjust the direction of suction force transmission;

[0037] The motor 19 drives the output end to rotate, and the output end drives the driving shaft 2 to rotate. Through the linkage of the belt, the driving shaft 2 drives the driving shaft 1 to rotate, and then drives the rotating shaft 27 to rotate. The rotating shaft 27 rotates inside the pump housing 18, and a suction force is generated inside the pump housing 18. The suction force acts on the connecting tube 5 through the suction pipe 4, enters the suction hood 7 through the filter screen 11, and is transmitted through the opening of the universal tube 8 to suck the dust at the location. The dust is intercepted by the filter screen 11, and is guided into the dust collecting box 2 through the guide plate 9, so that the dust is effectively collected. During the construction process, special dust suction devices are used for construction machinery, tools and equipment, etc., and the dust on the ground and equipment is cleaned in time to avoid dust generation.

[0038] Embodiment 2:

[0039] A travel plate 15 is provided on one side of the filter screen 11, and brushes 16 are equidistantly distributed at one end of the travel plate 15;

[0040] A rotating shaft 23 is rotatably installed inside the installation box 6, and a driven wheel 22 with a radius larger than the driving wheel 20 is sleeved on the outer wall of the lower end of the rotating shaft 23. A belt 21 is rotatably installed inside both the driving wheel 20 and the driven wheel 22.

[0041] A rotating shaft 34 is provided at one end of the cam plate 35, and a bevel gear 2 30 is sleeved on the outer wall of the rotating shaft 34. A bevel gear 1 29 meshing with the bevel gear 2 30 is sleeved on the outer wall of the upper end of the rotating shaft 27. A protective box 10 rotatably mounted with the rotating shaft 27 and the rotating shaft 3 34 and fixedly connected to the inner wall of one side of the mounting box 6 is sleeved on the outer side of the bevel gear 1 29 and the bevel gear 2 30;

[0042] The installation box 6 is provided with symmetrically distributed guide rails 36, and both ends of the guide frame 31 are provided with sliders 32 slidably mounted on the outer wall of the guide rails 36;

[0043] A cam plate 35 has a protrusion 33 slidably mounted inside the guide frame 31 at one end, a mounting plate 12 is provided at one end of the guide frame 31, and springs 14 equidistantly distributed are provided between the mounting plate 12 and the travel plate 15;

[0044] The mounting plate 12 is embedded with equally spaced sleeves 13, and the travel plate 15 is provided with a guide rod 17 which is slidably inserted into the sleeve 13 and located inside the spring 14;

[0045] In this embodiment, when the motor 19 drives the output end to rotate, the belt 1 21 is linked to the driving wheel 1 20 to drive the driven wheel 1 22 and the rotating shaft 1 23 to rotate. When the rotating shaft 1 23 rotates, the bevel gear 2 30 is pushed through the bevel gear 1 29 to drive the rotating shaft 34 to rotate. When the rotating shaft 34 rotates, the cam plate 35 is driven to rotate. Because the guide frame 31 slides on the outer wall of the guide rail 36 through the slider 32, the guide frame 31 is longitudinally guided. The protrusion 33 that rotates with the cam plate 35 and is located inside the guide frame 31 squeezes the inner wall of the guide frame 31, driving the guide frame 31 to move back and forth longitudinally, As the mounting plate 12 and the stroke plate 15 move, the brush 16 at one end of the stroke plate 15 scrapes the filter 11, and the dust adhering to the grid tube of the filter 11 is brushed off, thereby ensuring the smooth passage of gas through the filter 11. When the filter 11 is cleaned, the brush 16 gradually wears out, and the spring 14 elastically supports the stroke plate 15, so that the brush 16 always fits the filter 11, and the service life cycle of the cleaning component is extended, and the replacement frequency of the structural parts is reduced. The cleaning structure is driven by the motor 19, which is consistent with the power source of the suction force, thereby reducing energy consumption during use and complying with the concept of environmental protection.

[0049] S2: During the dust removal process, the base 1 of the dust removal equipment slides on the ground through the pulley 3, so as to be easily moved to the designated position, providing convenient movement conditions for the dust removal equipment for dust removal. The suction hood 7 can adjust the suction angle through the universal tube 8 to deal with the dust generated in the high or low space of the dust removal equipment;

[0050] S3: When the filter 11 intercepts the dust, the driving wheel 20, the driven wheel 22 and the belt 21 are linked to drive the shaft 23 to rotate, and the bevel gear 29 and the bevel gear 2 30 are linked to drive the cam plate 35 to rotate. The cam plate 35 is guided by the soil blocks on the side to squeeze the guide frame 31 installed to move back and forth longitudinally, thereby driving the brush 16 to scrape the filter 11 to remove dust. The filter component is automatically cleaned when the dust removal equipment is used.
